I can't display my index.php from my container due to this error:
Fatal error: Uncaught Error: Call to undefined function mysqli_connect() in /var/www/db/dbh.inc.php:8 Stack trace: #0 /var/www/includes/header.php(6): require() #1 /var/www/index.php(2): require_once('/var/www/includ...') #2 {main} thrown in /var/www/db/dbh.inc.php on line 8
The line 8 is: $conn = mysqli_connect($servername, $db_username, $db_password, $db_name);
I know that mysql_connect is deprecated in PHP 7.0, and I use here mysqli_connect
My Dockerfile from php-fpm run mysqli so I don't know what's wrong here
If my index.php show only a Hello World ererything is working well with Docker. Just to let you know my website is working well from my localhost without Docker.
If I want to connect to my db it's not working well with Docker.
In order to start the containers, I do docker-compose up -d
I have two questions:
1. How can I fix this issue ?
2. How can I start the db container always first before all others containers with docker-compose ?
